for each of the following unbalanced equations how many moles of thr first product are produced if 0.625mol of the second product forms.

calculate the mass in grams of the following samples.

a)4.24 moles of lead chlorde

g = mols x molar mass.

To determine the number of moles of the first product produced, we need to balance the given unbalanced equation. The number of moles of the first product formed depends on the stoichiometry of the reaction, which is represented by the balanced equation.

Since the equation is unbalanced, we need to balance it first. Please provide the unbalanced equations, and I will guide you through the process of balancing each equation.
